Degassing and dewatering of aggressive low-surface energy liquids. Research funded by the NSF and DOE has demonstrated successful membrane degassing of a variety of difficult to process liquids with low surface tension (oil, ink, petroleum hydrocarbons, solvents) or aggressive and corrosive properties (acids, etchants, inkjet inks. Certain corrosive gases, including (HF, HCl, NH3) can be separated from mixtures of gases and/or liquids with our membranes. Dewatering of certain aggressive liquid mixtures is currently being explored. Small ozonation systems for enhanced surface disinfection and biological/chemical decontamination of drinking water. Research funded by the NIH and USDA is presently underway to show that CMS membrane contactors safely introduce higher levels of bubble less dissolved ozone into water than injection methods, while potentially minimizing worker exposure to inhaled ozone off-gas. CMS has demonstrated oxidation of harmful contaminants with this ozonated water for applications such as the removal of humic acids, cryptosporidium, methyl tert-butyl ether (MTBE), and nitrobenzene from drinking water; as well as the disinfection of hard surfaces, such as medical supplies and dental unit waterlines, and the removal of pesticides from fruits and vegetables. Concentration of temperature sensitive beverages and pharmaceuticals. The process of osmotic distillation (OD) is being pursued for the dewatering of thermally labile aqueous streams, e.g. fruit beverages, coffee, and pharmaceuticals. OD can concentrate to very high levels at low temperature and pressure, with minimal thermal or mechanical damage to or loss of solute (product). Ongoing research is being funded by the NSF, NIH and USDA. Transportable generation of oxygen-enriched breathing air. CMS research funded by the NIH has demonstrated that 32% oxygen-enriched air is clinically equivalent to an oxygen prescription of 2 liters per minute of continuous flow oxygen for patients with chronic obstructive pulmonary diseases.
